There are many steps in the LED lamp production process. We’d like to introduce them briefly to you.
First, making semiconductor materials which is also called a semiconductor chip. Semiconductor materials are “grown” in high-temperature and high-pressure chambers. Elements such as gallium, arsenic and/or phosphorus are purified and mixed together in a chamber and then liquefied into a concentrated solution. After the elements are mixed, drop a rod into the solution and slowly pull it out. When pulled, the solution crystallizes at the end of the bar, forming a long cylindrical ingot.
The material is then cut into semiconductor wafers and basically polished, like a table, until the surface is smooth. It is then dipped into a solution of various solvents for a rigorous cleaning to remove any dirt, dust or organic matter.
Then, additional layers of semiconductor material are added to the chip.
Next, the metal contacts are defined on the semiconductor. This is determined at the design stage and takes into account whether the diode is used alone or with other diodes.
Finally, attach the diodes to the appropriate package, connect the wires, and then wrap everything in plastic.
Therefore, lots of equipment will be required during the LED light production.
1.About glue filling machine/glue filling machine
Lamp-led packaging is in the form of potting. The process of sealing is to inject liquid epoxy into the LED molding cavity first, and then insert the pressure welded LED bracket, put it into the oven for epoxy curing, and then release the LED from the cavity to form. It is called gluing, one of the LED packaging methods.
2.About the glue dispenser
LED light packaging equipment is a kind of colloid for the corresponding control, and the colloid in its specific form distribution/coating! Specialized automated control equipment “on” or “inside” of a particular product.
3.About crystal expander
Wafer expander is to evenly separate the tightly packed wafers so that they can be better implanted into the welder. It makes use of the heating plasticity of LED film and adopts the upper and lower control of double cylinders to evenly spread single LED chip around and automatically form after satisfying chip gap. The diaphragm is tight and unchanged.
4.About solid crystal machine
Packaging equipment, mainly used in the rapid fixing of chips.
5.About foot cutter
Finished follow-up equipment, mainly on diodes and other components of the pin cutting, bending finalize the processing. According to the different shaping devices, PLC control selection of different cutter operation.
6.About film removal machine
Packaging equipment for removing surface film in LED production, mainly used for removing film of digital tube, dot matrix board and light strip.
7.About the vacuum pump
Manufacturing process used to manufacture LED light emitting diode/digital tube, epoxy resin bubble removal equipment, its principle is: the air flow rate is very high when the pump high-speed rotation, the pressure becomes very small, in the diode to create a low pressure area, so that it is evacuated.
8.About baking oven
Solid crystal, sealant, test experiment, packaging defrosting drying tools, mainly vacuum drying, hot air drying and other types.
9.About Bunding Machine (wire welding machine)
Packaging equipment, the main role is to chip and circuit board welding.
10.About the scribing machine
Semiconductor production after the process of one of the equipment, mainly is to slice PCB board. However, laser scribing machine is mainly used in LED to replace the traditional mechanical scribing machine, mainly the characteristics of laser scribing machine and the particularity of products.
The production process used for wafer bunding machine, welding line amplification equipment, convenient for accurate welding, precise positioning. The most commonly used is the prick microscope.
12.About laminating machine
One of the packaging equipment, the main function is to evenly daub a layer of glue film on the module surface.
13.About glue sealing machine
Production process glue filling, dispensing after the chip sealing equipment, one of the bangding machine series of equipment.
